Açıklamalar

sınıfı NetworkChange , ağ kartı veya bağdaştırıcı olarak da adlandırılan bir ağ arabiriminin adresi değiştiğinde olayları tetikler NetworkAddressChanged .

Bir olay oluştuğunda NetworkAddressChanged bir NetworkChange nesnenin olay işleme yöntemini çağırmasını sağlamak için yöntemini bir NetworkAddressChangedEventHandler temsilciyle ilişkilendirmeniz ve bu temsilciyi bu olaya eklemeniz gerekir.
